ROOFING-SEAMER.

SPECIFICATION forming part of Letters Patent No. 455,177, dated .Tune 30, 1891. Application filed February 12, 1891. Serial No. 381,256. (No model.)

.To all whom t may concern:

Be itknown that I, RICHARD R. DELANEY, residing at Charleston, in the county of Kanawha and State of West Virginia,l have invented certain new and luseful Improvements in Rooing-Seamers, ot' which the following is .a specification.

the edge of the seam down, ready to be clampedand finished by the tongs.

My invention further consists in the peculiar combination and novel arrangement of the several parts, all of which will hereinafter be fully described in the annexed specification, and particularly pointed outin the claims, reference being had to the accompanying drawings, in whichp Figure l is a perspective view of my improved roofing-seamen Fig. 2 is a transverse section thereof on line 2 2, Fig. l. Fig. 3 illustrates the seamer clamping the ends of the metal and upsetting the longer end. Fig. 4 shows the seamer as turning the seam. Fig. 5 shows the seamer clamping the ends together to form a single seam; and Fig. 6 is a detail view, hereinafter referred to.

In the accompanying drawings, A indicates the main or abutment jaw, which is pivotally connected with the clamping-jaw B in the usual manner, said jaws A andB being formed with socketed tongs A and B, in which are t` ted the stems a and l) of the hand-holds A2 and B2, as shown. The abutment-jaw Aisformed at one edge with a right-angle projection a2, under which the longitudinal member b of the jaw B operates, and at its opposite edge with an outwardly-extendingrib or extension a3, having a convexed face, in which is hinged the folding-bar O, which operates against the face co4 of the jaw A, which face, it will be seenl is of a less height than the opposite or clamping-face d5. The folding-bar C is formed with an upwardly and outwardly curved` member C', which is connected by means of a pivoted link D with an ear a6 von the jawsection B, as shown.

l E E indicate apertured ears extended from the rear edge of the lower portion of the tongs B', in which is journaled a grooved roller F, which is preferably formed with a groove having a straight part f and a beveled part f', for a purpose presently explained.

The manner in which my improved seamer is used is clearly illustrated in Figsx, 4., and 5 ofv the drawings, by reference to which it will be seen that the ends of the metal are first clamped between the jaws A and'B, the

relation of such jaws being such that the long end 10 of the metal will be bentat right angles over the short end 20, asshown in Fig. 3. After the ends have been bent and pulled together in the manner stated the seamer is turned sidewise, with its grooved roller on the upper bent end l0, and pressure being applied thereto it is run along the entire length of the bent end, which operation serves to turn the end 10 over the end 2O to the position clearly shown in Fig. tot the drawings. It will also be noticed by reference to said figure that by making the groove in the roller with a straight edge f such edge formsa guide against the vertical edge of the metal, the bevel-face f serving to turn said end l0, as stated. rlhe machine is then turned and the bent end l0 and the end 20 are then Lclamped between the jaw A and the folding-bar C, which operation serves to complete the single seam.

It will be understood by reference to the drawings that the relation of the jaws A and B and the bar C with the tongs A and B is such that the jaws A and B will be operated to clamp the metal as the tongs are closed v together, and the jaw A and the bar C operate to clamp the metal as the ton gs are spread apart.

In the practical operation of my invention when it is desired to form a double seam, two of my improved seamer-tongs are provided,

IOO

one of which is formed with jaws one inch higl1,wl1ich serve to form the single seam, after which the said single seam is again folded in precisely the same manner as before by the other seamer, which has jaws of about threefourths of an inch high.

lVhile I prefer to employ a roller having a groove formed as stated, it is manifest that a roller formed with a regular groove (see F, Fig. G) may be employed.

From the foregoing description, taken in connection with the drawings, it will be observed that I dispensewith the foot-lever and operate all the jaws by the two tongs, thus providing a seainer which can be used on inclined roofs and on Vertical metal-covered walls, where foot-operated machines cannot be employed.

Having thus described my invention, what lolaiin, and desire to secure by Letters Patent, 1s

1. The combination, with the pivoted clam ping-tongs A and B', arranged as shown, of a grooved roller journaled in one of the jaws and arranged for upsetting or turning the bent edge of the metal, as and for the purpose described.

2. The combination of the clamping-tongs A and B', arranged as shown, of the pulley F, journaled in one of the jaws at right angle thereto, said pulley formed with circumferential groove having a straight portion f and beveled portion f', substantially as and for the purpose described.

A rooiing-seamer consisting of a central jaw A, formed with clamping-faces a and a5 on its opposite sides, the clamping-j aw B, said jaws A and B formed with tongs pivotally connected, as shown, a folding-bar C, hinged to the outer edge of the central jaw A, the linkconnection D between the bar C and the tongs of jaw A, and the grooved tu rnin g-roller jou rnaled to the outer edge of the jaT B and arranged at right angles to the said jaw, all arranged substantially as and for the purpose described.
